How Do I Disable a User in Exchange 2016?

You can disable a user in Exchange 2016 using the Exchange Admin Center (EAC) or the Exchange Management Shell.

Using the Exchange Admin Center (EAC)

2. Navigate to the "Recipients" section: In the left-hand menu, click on "Recipients" and then select "Users."
3. Select the user: Find the user you want to disable and click on their name.
4. Disable the user: In the user's properties window, go to the "Account" section and uncheck the "Enabled" checkbox.
5. Save the changes: Click on "Save" to confirm the changes.

Using the Exchange Management Shell

1. Open the Exchange Management Shell: Open the Exchange Management Shell on your Exchange server.
2. Run the Disable-Mailbox cmdlet: Use the following command, replacing "<username>" with the user's account name:

Disable-Mailbox -Identity "<username>"

Additional Notes

• Disabling a user in Exchange 2016 will prevent them from accessing their mailbox and sending or receiving emails.
• The user's mailbox and other data will still be stored on the Exchange server.
• You can re-enable a disabled user at any time by following the same steps but checking the "Enabled" checkbox in the EAC or using the Enable-Mailbox cmdlet in the Exchange Management Shell.
